"Truth is, all these methods can work" states the summary of that article in Slate.
What they failt to mention is that the TV show has a disclaimer to not try them at home. The reason? The techniques are dangerous 'in the wrong hands'. Not only that, they are not recommended by professionals (true professionals) because they can damage a dog. Some dogs may 'adapt' to his aversion techniques being used on them. Others will shut down and crumble, others will bite or bcome neurotic.
Many will look like they have adapted and are 'behaving'. I liken it to using negative punishment on children. Would you not rather foster a positive, rewarding, mutually enjoyable relationship with your kids than a domineering, rule-through-fear relationship?
Shut down a dog so that it is too frightened to communicate to you when it is anxious (such as growling, or moving), and you will end up with a dog pushed beyond its comfort zone that then becomes unpredictable.
Communicate with your dog. Respect that it is a dog, it has needs, it has emotions (different to ours but still there). You will get so much more out of your dog that way, and your relationship will be so much richer for it.
I am wasting my breath.
